Description
Technical Field
The utility model relates to a measurement auxiliary device, in particular to an orthogonal scale stand which is simple in structure and convenient to operate.
Background
When in geodetic measurement and engineering measurement, the measurement staff (leveling staff, total station reflecting prism centering rod, satellite positioning measurement centering rod and the like) needs to be erected on the measurement mark point to keep vertical and face the measuring devices such as the leveling instrument and the like, so that measurement can be performed, namely the vertical state of the measurement staff and the deflection angle of the leveling instrument directly influence the measurement precision. The outer base of the conventional measuring foot rest (tripod) is in a flat plate shape, and cannot be applied to a measuring staff, so that a measurer is required to walk to operate, namely, the measurer adjusts the measuring staff by observing whether bubbles of the level are centered or not, and the measuring staff is in a vertical state by walking, so that time and labor are wasted, accurate leveling is difficult to ensure, and measuring accuracy is reduced. In order to solve the above problems, the chinese patent No. 201220373858.9 discloses a "jacket clip type measuring stand", which mainly contributes to changing the outer base of the conventional stand from a flat plate (cradle head type structure) to a ring (jacket clip type structure), providing a special measuring stand for the measuring scale for the first time, and improving the accuracy of the vertical direction of the measuring scale. The Chinese patent with the patent number of 201310022381.9 discloses a clamp type measuring foot rest, which is further improved by adopting an orthogonal decomposition adjustment principle, so that the adjustment speed of the scale in an upright state is increased. The specific operation process is that firstly, the measuring staff is placed in the base, the measuring staff is fixedly connected with the base through the fixed connection device, the bottom of the measuring staff is placed on the measuring mark point and approximately faces the level gauge, then the external opening angle and the length of the supporting legs are adjusted, the measuring staff is erected to be stable and approximately vertical, and then the measuring staff can be accurately in a vertical state through fine adjustment of the jackscrews. The Chinese patent No. 201610159164.8 discloses a measuring foot stand capable of accurately adjusting the angle of a ruler, and further solves the problem of horizontal rotation and aiming face after the ruler is straightened. However, the above-mentioned measuring foot rest has the following disadvantages in practical application: (1) The support legs of the orthogonal foot rest used at present are positioned in the longitudinal direction and the transverse direction of the rectangular staff, so that a measurer can eccentrically stand and lean on the foot rest during use, and long-time measurement work is not facilitated; (2) The staff level is fixed with the staff and not fixed with the foot rest, when the staff rotates and then adjusts the staff to be in an upright state, the inconformity of the bubble direction of the L-shaped level and the direction of the foot rest (or supporting leg) adjusting screw can occur, and the quick alignment of the staff is affected.
Disclosure of Invention
The utility model aims to solve the technical problems in the prior art and provides the orthogonal scale stand which is simple in structure and convenient to operate.
The technical scheme of the utility model is as follows: an orthogonal scale foot rest is provided with an opening annular base, a rectangular opening scale ruler seat is connected to the inner side of the opening annular base through vertical shaft rotation, a spring is arranged between the opening annular base and the rectangular opening scale ruler seat, a transverse jackscrew is arranged on the opening annular base, the front end of the transverse jackscrew is propped against the front end of the right side face of the rectangular opening scale ruler seat, two transverse screws which are connected with the opening annular base in a rotation mode and are orthogonal to the axis on a horizontal plane are uniformly distributed on the opposite face of the opening annular base and the opening, a guide rail which is coplanar and parallel to the transverse screws is arranged on the transverse screws, a sliding block which is connected with the transverse screws in a threaded mode is sleeved on the guide rail, a sliding locking device is arranged on the sliding block, a connecting piece which is perpendicular to the transverse screws on the horizontal plane is arranged on the sliding block, a supporting leg is connected with the connecting piece in a radial rotation mode, a telescopic device is arranged on the supporting leg, and two tube leveling devices which are parallel and orthogonal to the axis of the transverse screws are also fixed on the opening annular base.
The utility model has simple structure, the adjusting screws and the supporting feet of the foot rest are uniformly distributed on the opposite surfaces of the opening annular base and are in orthogonal distribution, thereby not only ensuring the quick alignment of the staff gauge, but also effectively avoiding the eccentric standing and sideways operation problems of the measurer and being convenient for operation; meanwhile, the leveling instrument is directly fixed with the foot rest, so that the difficulty that the bubble direction of the L-shaped leveling instrument is inconsistent with the direction of the foot rest (or the supporting foot) adjusting screw is avoided, the operation of a measurer is easier, and the working efficiency of leveling measurement is improved.
